Lead Chloride Precipitation

Pb(NO₃)₂ + 2NaCl → PbCl₂↓ + 2NaNO₃

Genel Bakış

Lead nitrate reacts with sodium chloride to form a white precipitate of lead chloride (Ksp = 1.7 × 10⁻⁵). PbCl₂ is moderately insoluble at room temperature but becomes quite soluble in hot water, distinguishing it from AgCl. The precipitate consists of fine needle-like crystals.
